win2k3 sever, disable cluster node

[jason idleman]

some how in my set up of the DHCP/DNS server, I have told this thing it is a node in a cluster. It isn't. Now I can't use my "Manage your Server" to administer it. I have read the help files, they don't tell me how to turn clustering off, only on.
I open cluster administrator and there is nothing for it to find.
I'm lost, and frustrated.

Looks like you can "unconfigure" it, but you can't uninstall it anylonger. :-(

I tested it on my Vmware virtual 2003 test-server running a one-node cluster.

As Jon wrote cluster files are installed by default, but that does not mean DHCP _has_ to be installed in the cluster.

Tested
------
*Had DHCP installed locally & working fine.
*Installed a one node cluster
*Made new DHCP resource in the cluster
- Selected same db-path
- Old DHCP server gone
- New Virtual clustered DHCP available via DHCP manager - must be authorized because of new network name (if you want to actually use it).
- Same options as standalone via DHCP manager.
- Scopes from standalone DHCP available (because same db-path was selected)

Next to try to get back to standalone DHCP:
--------------
*Deleted DHCP resource in Cluster Adm
- New or Old DHCP not accessible via DHCP manager
*Control Panel -> Network Svcs still show DHCP checked
* My Computer -> Manage -> Services show DHCP Service now has Manual startup and is stopped
* Start DHCP service and configure Automatic start
* DHCP manager to local node name -> Old scopes still available and server still Authorized in AD - shows that selecting the same DB-path when defining the cluster DHCP resource did not delete the existing databases. Interesting, but I would always recommend having a backup.

For backup see:

So to summarize how to get from a clustered DHCP to a standalone:
1) Backup DHCP
2) Delete DHCP resource in Cluster Admin
3) Set DHCP service to Automatic startup and start the service
4) Use DHCP manager again
5) Restore DHCP
